Red Dwarf star Robert Llewellyn is an inveterate Mac user, so it's no suprise he's decided to act as the talking head for a short series of video clips explaining some of the features of Parallels for Mac.

A pair of clips published on YouTube by Computer Warehouse see Llewellyn explain the machinations of the virtualisation software, which lets Intel Mac users run Windows side-by-side with Mac OS X.

The clips reflect the 'Get A Mac' ad format and see Llewellyn explaining the advantages of the virtualisation software.

In No Reboot, he discusses the advantages of Parallels over and above those of Apple's own Boot Camp software. While in Split Personality he looks at the notion of running both operating systems at once.
